When a fluid passes through a constricted part of a pipe ,what happens

1.	When a fluid passes through a constricted part of a pipe ,what happens to its velocity and pressure ?
Answer» <P> Solution :When a FLUID passes through a CONSTRICTED part then according to `vprop(1)/(A)` its velocity increases and according to Bernoulli.s equation `P_(1)+(1)/(2)rhov_(1)^(2)=P_(2)+(1)/(2)rhov_(2)^(2)` PRESSURE decreases .
